Industrial Electrical Installations Virtual Course (DL SMART-INDUSTRIAL)

1. EFFECTIVE GUIDE FOR STUDENT

Possibility to access learning topics, with theory, instructions, and experiment proposals. The software includes a virtual version of the DE LORENZO Electrical industrial installations didactic systems; Student logs in, so his progress can be tracked, chooses one of the learning topics, accesses theory, experiments proposals and instructions.

2. AUTOMATIC VALIDATION OF STUDENTS’ TASKS

The software automatically verifies if the student has completed successfully each task in order to allow him/her to go ahead with the next one. Student works on the assembly of the electrical machine, then makes the electrical connections and with all that correctly done, runs the experiment and answers questions about it

IT CONNECTS PROFESSOR, STUDENT, AND SCHOOL

De Lorenzo´s cloud server receives the students’ activities and provides reports and analytics to professors and institutions. Besides, a student can start working at school and continue at home or vice-versa. That means that the professors can monitor the students and based on the report that De Lorenzo´s cloud provides, the professors can give the support that a specific student might be needing.

COMPATIBLE WITH THE DL SMART-DASHBOARD (SOLD SEPARATELY)

PROFESSORS CAN FOLLOW STUDENTS PROGRESS

The professor can do and access everything the student can. Besides, he/she can also access the dashboard’s portal. It includes interesting reports and analytics that help the professor to monitor the group in real time, as well as to identify students who are doing very well, as well as those who need help, who are not working at all and who seem to be “cheating”.

Tasks report

This is an important tool since it provides evidence of the activities a student worked on. That means the school has evidence of the practical activities the distance learner has done with detailed information about it.

PROFESSORS CAN SEE WHICH STUDENTS ARE ON SCHEDULE

With this interface, the professor may choose which groups he/she wants to monitor, to verify who is on schedule, who is pending and so on. It is possible to define the expected progress percentage in relation to the tasks available in the course.

RHYTHM

This other dashboard shows the number of activities the students did daily and weekly. The professor may decide to verify it regarding a whole group/class or a specific student.

TRIALS PER TASK

This chart helps the teacher to understand which task may be the most difficult and which one may be the easiest in order to adjust the deadlines.

• IT’S A 3D SIMULATOR
• IT HAS BUILT-IN EXPERIMENTS
• THE PROJECTS INCLUDE GUIDANCE
• + CONTENTS AND SUPPORT MATERIALS, SO THEY CAN LEARN BY THEMSELVES
• IT AUTOMATICALLY CHECKS STUDENT ACTIVITIES TO LET THEM MOVE ON, LIKE IN A GAME
• PROFESSORS CAN MONITOR STUDENTS AND VERIFY WHICH POINT THEY NEED HELP(Option available with the Dashboard)

HOW DOES IT HELP THE PROFESSOR?

With this software, the teacher spends less time explaining topics, verifying students’ activities and helping students to identify mistakes that do not allow the successful completion of the experiment.

That means that the professor has more time to manage the class, help students who need more attention and make improvements. The two following points grant such benefits:

1. The software automatically verifies the experiments carried out by the students and it gives relevant feedback:

Like in a game that has different phases with challenges and missions, the DL ELECTRICAL INSTALLATION software includes practical experiments that need to be successfully completed to let the student access the next one.

The teacher does not need to verify continuously if the student carried out the experiment. Moreover, many questions students would make about “What could be wrong?” are automatically “answered” by the software when the student does not perform the experiment successfully. The image below summarizes this process.

2. The software tracks the students’ progress, and it allows exporting reports:

At any time, the professor may verify how many and, specifically, which experiments the student has completed. That report can be used to track students’ activities and it can be considered as an evaluation tool.

This report can be generated and displayed directly in the system or it can be exported to a spreadsheet (see image below).
